2. VCCB (Pin 2) - Positive supply voltage for the high side (I2C bus on the other side).
3. GND (Pin 3) - Ground connection.
4. SCL1 (Pin 4) - Low side SCL input/output.
5. SDA1 (Pin 5) - Low side SDA input/output.
6. SCL2 (Pin 6) - High side SCL input/output.
7. SDA2 (Pin 7) - High side SDA input/output.
8. N/C (Pin 8) - No connection.
This device allows for communication between I2C devices operating at different voltage levels, facilitating interoperability in mixed-voltage systems.
